Figure 5 is a vertical transverse sectional view taken substantially onthe line 55 of Figure 1, looking in the direction indicated by thearrows.

Figure 6 is a group perspective View illustrating the cam elements ofthe transfer mechanism of the machine.

The machine embodying the invention includes a frame structure embodyinga base or foundation 1. corner uprights 2, longitudinal side members 3,which extend between the uprights 2 at the opposite sides of thestructure, side members 4 which extend between the upper ends'of theuprights 2 at the opposite s1 es of the structure, a table 5 supportedbetween the uprights 2 and above the base 1, and cross braces 6 whichextend transversely between the side members and beneath the said table5 and which serve not only to brace the said uprights but also serve asa support for the sand table. The numeral 7 indicates a hopper for theballs to be dipped, and this hopper 1s supported between bracket arms 8whlch are located at the opposite sides of the hopper and are secured inany suitable manner to the rear uprights 2 of the frame. The numeral 9indicates a trough which contains the paint with which the balls are tobe coated. and this trou h extends between the rear uprights 2 of t eframe structure and is supported thereby and by the side members 3 ofsaid structure. For a purpose to be presently expla ned, the trough 9comprises a main body lncludmg a rear wall 10, a front wall 11, endwalls 12, and a bottom 13, and the trough is rovided at its front withextensions 14 eac including side walls.15, a front wall 16, and a bottom17, so that paint delivered to the body of the trough will flow into andoccupy the said extensions 14 as clearly shown in Figure 3 of thedrawings, the bottoms 17 of the several trough extensions being in thesame plane as the bottom 13 of the body of the trough, and the said bodyof the trough and the said trough extensions being open at their tops.The numeral 18 indicates runways which lead from the hopper 7 in aforward and slightly downwardly inclined direction and have theirdelivery ends 19 located within the body of the trough near the topthereof, these runways serving to conduct the balls, to be dipped, fromthe hopper 7 to the trough, and the said balls being adapted to roll bygravity down the said runways and to follow one another in the mannerclearly shown in Figures 1 and 3 of the drawings. The inventioncontemplates the delivery of the balls, which are indicated by thereference letter B, one by'one, to the extensions of the troughs by adipping mechanism which will now be described.

The dipping mechanism referred to above comprises a ball receivingmember which is indicated by the numeral 20 and is of hollowsemi-cylindrical form except at its ends, where it is provided withcylindrical portions 21 to accommodate cylindrical bushings 22. A shaft23 is fitted axially through openings in the bushings and is yournaledat its ends in bearing openings 24 formed in the side members 3 of theframe Structure, the shaft being of a diameter less than the diameter ofthe semi-cylindrical receiving member .20 and havin its upper sideflattened throughout its length except at its ends, as indicated by thenumeral 25. Crank arms 26 are secured at their inner ends to the outerends of the shaft 23 outwardly of the frame structure, as clearly shownin Figure 2 of the drawings. It will be observed by reference to Figure3 of the drawings that the open side of the receiving member 20 ispresented upwardly and that the member is to be rotated from the fullline position shown in the said figure to the dotted line shown therein,during the dipping operation. It will l kewise be observed by referenceto the said Figure 3, that when the receiving member 20 is in the fullline or receiving position, one side 27 of the member will extendrelatively close to the delivery ends 19 of the runways 18 andsubstantially in a plane with the bottoms of said runways. At this pointit will be understood that the receiving member is to be continuouslyoscillated in the operation of the machine and that, therefore, it willonly momentarily assume the position shown in full lines in Figure 3, atwhich time the foremost ball in each runway will roll to the positionshown in said figure with its lower side resting against the upper sideof the shaft 23 and the edge or side 27 of the receiving member. Thereceiving member supports, substantially in alinement with each runway,a dipper indicated by the numeral 29, and preferably made of wire rodmaterial and comprising spaced parallel side members 30 which at theirrear ends are secured, as at 31, through the side of the member 20 whichis located next adjacent the delivery ends of the runways 18, the saidside members 30 being extended at this point, across the member 20 in aforward direction and through the shaft 23 and thence forwardly beyondthe receiving member for a suitable distance. The forward portions ofthe side members 30 are then curved upwardly in parallel relation toeach other, as indicated by the numeral 32. to provide an abutment orrest for the balls to be dipped, the upper ends of the portions 32 beingconnected by a forwardly bowed ortion of the wire from which the dipperis ormed, indicated by the numeral 33, so that the spaced side membersof the dipper are relatively braced. It will be observed by reference toFigure 2 of the drawings, that the extensions 14 of the trough arelocated substantially in alinement with and in advance of the runways 18and that the dippers 29 are to operate within said trough extensions.

Through mechanism to be presently described, oscillatory motion is to beimparted to the receiver 20 to effect lowering of the balls, in thetrough extensions, for dipping,

and a subsequent elevation of the said balls. By referring to Figure 3of the drawings, it will be observed that the balls are permitted totravel down the runways until the foremost ball assumes a positionresting upon the receiver, the receiver and the dipper being at suchtime in the full line position shown in Figure 3, the presentdescription referring to a single one of the runways and dippers,although it will be understood that any number of dippers may beemployed and that all will operate in unison. From the elevated positionshown in full lines in Figure 3 of the drawings, and as the receivingmember 20 is oscillated toward its dotted line position, it will assumefirst the slightly rotated position shown in Figure 3, in which positionits side which is next adjacent the delivery ends of the runways 18,will be elevated somewhat above the bottoms of the runways so that, inthe continued movement of the receiving member in this direction, saidside will offer an obstruction to the second ball in line. Likewise inthis continued movement of the receiving member, the dipper 29 will belowered and the ball which has been taken up by the receiving memberwill be permitted to roll by gravity down the side members of the dipperuntil it comes to rest against the members 32 thereof. As the dipperreaches the full lowered position shown in the lower dotted lineillustration in Figure 3, .the ball will be immersed in the paint in therespective trough extension 14. At this time, the receiving member 20will be oscillated in the reverse direction, thereby elevating thedipper and the ball carried thereby. Mechanism to be presently describedthen operates automatically to pick up the dipped ball immediately priorto the time the receiving member and dipper reaches the full lineposition shown in Figure 3, at which time the ball then foremost in therespective runway 18, may roll onto the receiver, as previouslydescribed.

Paint is supplied to the trough 9 from a reservoir 34 mounted upon thebrackets 8, and by way of a pipe 35 which leads from the bottom of thereservoir into the said trough through the rear wall 10 thereof, a valve36 being interposed in said pipe and adjustable to control the supply ofpaint.

The drive shaft of the machine is indicated by the numeral 37 and thesame is journaled in suitable bearings upon the side members 3 of theframe structure and carries a pulley 38 about which is trained a belt 39driven from a suitable source of power (not shown). Fixed upon the outerends of the said shaft 37 are pinions 40 which mesh with gears 41rotatably journalcd upon the outer ends of a shaft 4.2 which is mountedin the side members 3 of the framestructure and projects at its oppositeends beyond the said side members. A crank arm 43 is fixed to tit" Inn

llU

lla'i the outer end of the hub 44 of each respective gear 41 so as torotate in unison therewith and about the shaft 42, and a connecting rod45 is connected at its ends to the crank arms 26 and 43 at the op ositesides of the machine. It will be observed by reference to Figure 1 thatthe crank arm 43 is of less length than the crank arm.26 so that whilethe arm 43 rotates continuously. the arm 26 is oscillated so as toimpart oscillatory motion to the receiving member 20, as previouslyexplained.

After the golf balls have been dipped, they are to be deposited upontrays which trays will presently be specifically described, and means isprovided for transferring the dipped balls from the dippers to the traysand imparting rapid rotary motion to the balls during the period oftransfer. The transferring mechanism is best illustrated in Figures 2, 3and 4 of the drawings, and is mounted upon the shaft 42. This mechanismincludes transfer units equal in number to the number of dippers andoperating immediately 1n advance of the respective dippers, the transferunits being indicated in general by the numeral 46. Each of these unitscomprises a set of cams including an intermediate cam v47 and movablecams 48 located at the opposite sides thereof. The cam 47 comprises asubstantially semi-annular portion 49 which is of uniform widththroughout its extent, and a body portion 50 likewise of substantiallysemi-annular form and having oppositely laterally disposed cam portions51, the cam edges of which are indicated by the numeral 52. The portions51 have abrupt transverse faces 53 at their widest portions and aregradually decreased in Width, due to the contour of the working edges52, so that the said working edges of the cam portions 51 extend fromthe outer ends of the abrupt faces 53 on a substantially helical curveand merge with the opposite edges of the cam portions 49. The cam member47 is keyed or otherwise fixed upon the shaft 42 with the abrupt faces53 thereof presented substantially toward the dippers and assumingsubstantially the position shown in Figure 3 of r the drawings. Theworking edges of the portions 51 of the cam 47 have substantiallystraight portions 54 which merge with the respective edges 52 and extendto the abrupt faces 53. Each of the cams 48 comprises a cylindrical'body55 supporting, at its outer end, a radial arm indicated by the numeral56, the bodies of the said cams 48 being both slidably and rotatablyfitted onto the shaft 42 at the opposite sides of the cam 47 Each cambody 55, at its end which opposes the cam 47, has a working edge or face56 which extends substantially three-fourths of the circumference of thecam body and occupies a plane substantially at right angles to the axisof the body. The other fourth of the circumference of the cam body atits said end is short stub shaft 72 occupied by a cam portion 57 havingan abrupt face 58 and a curved face 59 which extends between the outerend of the face 58, inwardly, and merges with the working edge 56, itbeing understood that the cam portions 57 are to ride against the cam'edges of the cam 47 in the rotation of the cams 48. A tension spring 60is connected at its ends to lugs 61 upon the inner sides of the arms 56and yieldably holds the cams 48 in operative relation to the cam 47, itbeing understood that as the cam portions 57 of the cams 48 ride overthe workingedges 52 and 54 of the cam 47 separation of the arms 56 takesplace against the tension of the spring 60 and that the said spring willact to immediately draw the cams 48 and their respective arms 56 towardeach other at the moment the outer ends .of the portions 57 of the saidcams 48 ride past the outer ends of the abrupt faces 53 of the portions51 of the cam 47. In order to guide the arms 56 in their relativemovement and prevent displacement of the arms,

a pin 62 is secured at one end in one of the arms, preferably radiallyoutwardly of the spring 60, and is slidably engaged at its other endportion through an opening 63 formed in the other arm. In order thatrotary motion may be imparted to the cams 48, gears 64 are freelyrotatably mounted upon the shaft 42 immediately inwardly of the sidemembers 3, and support abutment members 65, these members being ofarcuate form in cross section and extending longitudinally of and inspaced relation to the shaft 42 and being mounted and secured at theirends upon the hubs 66 of the said gears 64. The relatively adjacentedges of the members are so spaced as to accommodate between them thearms 56 as clearly shown in Figures 2, 3 and 4 of the drawings. A pinion67 is secured upon each end of the power shaft 37 inwardly of therespective side member 3 and meshes with the respective gear 64 and itwill, therefore, be evident that as the shaft 37 is rotated, rotarymotion will be imparted to the gears 64 and, through the medium of thedriving members 65, rotary motion will be imparted to the cams 48 toeffect rotation of transfer devices of which the arms 56 constitute apart.

Each of the transfer devices comprises, in addition to the arms 56, ballgripping members indicated one by the numeral 68 and the other by thenumeral 69. The member 68 comprises a body 70 having the form of apulley, the grooved periphery of which is indicated by the numeral 71.and the said body is provided concentrically at its outer'face with ajournaled in an opening 7 3 formed in the adjacent arm 56. The shaft 72has a cylindrical enlarged portion 74 which has a conical outer end 75constituting a tapered journal having bearing in a conical bearing seat76 formed in a bearing bracket 77 mounted upon the outer side of the arm56. Studs 78 are threaded into the inwardly presented face of the pulleybody of the gripping member 68 and are preferably disposed at an angleoblique to the axis of rotation of the said member, the said studs 7 8being symmetrically concentrically arranged about the axis of the member68 and having sharply pointed tapered ends 79 which are designed toengage one side of the ball B which is to be grasped by the transfermechanism and carried from the dipper't-o the tray. The member 69comprises a relatively flat circular body 80 having a stub shaft 81 uponits outer side and rotatably mounted in an opening 82 in the respectivearm 56, this shaft beingprovided with a cylindrical enlargement 83 atthe outer side of the said arm and terminating in a conical or taperedjournal 84 which engages in a conical bearing 85 formed in the innerface of a bearingbracket 86 mounted upon the outer side. of therespective arm 56. Studs 87 corresponding to the studs 78 are threadedinto the inwardly presented side of the body 80 and are symmetricallyconcentrically arranged with relation to the axis of the shaft 81 andhave tapered pointed ends 88 designed to engage the other side of theball to be held and supported. Any desired number of the studs 78 and 87may be provided, .but there will preferably be three in each set ofstuds.

In order that the coated or dipped balls may be rapidly rotated duringthe transfer period in order to evenly ditstribute the paint over theirsurfaces, means is provided which will now be described. The numerals 89and 90 indicate shafts which are rotatably journaled in suitablehearings in the side members 3 of the frame structure of the machine,and a series of pulleys 91 and 92 are mounted upon the shafts 89 and 90respectively, belts 93 preferably of the round type, being trained aboutrespective pairs of the pulleys and the arrangement being such that thelower stretch of each belt 93 will be located in a vertical plane withthe groove 71 of one of the transfer gripping members 68. A pulley 94 isfixed upon the shaft 90, and a belt 95 is trained over the pulley anddriven from any suitable source of power so that rapid rotary motion isimparted to the shaft 90, and the belts 93 are caused to rapidly travelabout and between the pulleys 91 and 92. Likewise. the arrangement issuch that as the gears 64: are rotated and rotary motion is imparted tothe transfer units, the grooved peripheries of the gripping members 68of the units will, during a period in the rotation of the units, rideagainst the lower stretches of the respective belts 93 and, inasmuch asthesebelts are being driven at a high rate of speed, the ball which isgripped between the gripping members 68 and 69 will be rotated at a highrate of speed, thereby, through centrifugal force, evenly distributingthe paint upon the surface nesaso1 of the ball in a thin film forcoating the said surface, and, at the same time, throwing off from thesaid surface, any surplus paint. B reference to Figure 2 of thedrawings, it wi i be observed that the transfer units are so arrangedupon the shaft 42 that they will rotate immediately in advance ofrespective dippers 29 and that in the rotation of each unit, thegripping members 68 and 69 thereof will travel upwardly past and atopposite sides of the forward end of the respective dipper. Thearrangement of the cams is such that when the dipper :29 has nearlyreached the full line position shown in Figure 3 of the drawings, theends of the cam portions 57 of the cams 48 will ride over theextremities of the cam portion 51 of the cam 49 and the spring 60 willthen act immediately to move the arms 56 and the gripping members 68 and69 carried thereby, toward each other, and cause the pointed extremitiesof the studs 78 and 87 to engage the opposite sides of the ball which isat such time supported by the dipper and has at that time been elevatedfrom the paint trough. Therefore, the ball will be immediately firmlygripped without, however, injuring the same or marring its surface andwithout disturbing the paint upon said surface inasmuch as theextremities of the studs are sharply pointed and there is, therefore, noappreciable surface engagement of the gripping members with the o positesides of the ball. It will likewise )e understood that in the continuedrotation of the cams 48, the arms 56 will be carried around with arotary motion in a forward and upward direction as the ends of the camportions 57 ride along the opposite edges of the portion 49 0f the cam47, and it is during this period of rotation of the transfer unit, thatthe ball which is held between the gripping members is rapidly rotatedthrough engagement of the grooved periphery of the member 68 with thelower stretch of the respective belt 93, so that, as previously stated,the paint is evenly and uniforml distributed over the surfa e of theball. s the cams 48 continue to rotate and as the ends of their portions57 ride into engagement with the working edges 52 of the cam portions 51of the cam 47, a separation of the grip ing members 68 and 69 will beeffected and t e ball will be released, being deposited, at such time,upon one of the receiving trays which will presently be described. Inthe meantime, the dipping mechanism has been automatically operated, inconsonance with the operation of the transfer mechanism, to effectdipping and elevation of the next ball to be treated.

In order to prevent the paint which is thrown off, by centrifugal force,from the balls, as they are rapidly rotated, being deposited on theoperating parts of the mechanism, a transversely concave sheet metalshield 96 is arranged above the actuating Inn cams of each of thetransfer units and concentric with respect to the shaft 42, the shieldbeing fixedly mounted at one end as at 97, upon the front wall 16 of theres ectlve trough extension 15, as best shown in igure 3 of thedrawings, and this shield is so arranged that its transversely concaveside will be presented toward the under side of the ball which is beintransferred and rotated, so that none of the paint will be thrown ontothe cams. A similar shield 98 is mounted above and concentric to therespective shield 96 and, therefore, the balls which are being treatedare carried beneath this shield, the shield being transversely concaveand supported by a suitable cross piece 99 constitutmg a part of theframe structure.

The trays for receiving the coated golf balls, and heretofore referredto, are indicat-ed in general by the numeral 100 and are mounted uponthe table 5 of the machine. Each of the trays comprises arectangularshallow body including a bottom 101 and upstanding walls 102, the saidtable 5 belng provided upon its upper side and at 1ts longitudinal'edgeswith upstanding flanges 103 between which the trays are confined and bywhich they are guided in their movement over the table through theoperation of meansto be presently described. The numeral 104 indicates anumber of bridge members which are mounted transversely within each trayand these bridge members may be formed from sheet metal and are arrangedin spaced parallel relation and each includes a top portion 105 anddepending end portions 106 riveted or otherwise secured to theupstanding side walls of the tray. A series of sets of studs 107 arearranged upon the top port on 105 of each bridge member, the studs beingthreaded into openings formed in the said top portion 105 and havingtapered pointed ends 108, the studs of each set being symmetricallyarranged about a common center and lnclined upwardly and inwardly sothat a coated golf ball deposited upon the polnted upper ends of thestuds of any set will be firmly supported in position and yet withoutany appreciable surface contact whlch would tend to disturb the coatingof paint upon its surface. It will be observed by reference to Figure 2,that the arrangement of the sets of studs 107 is such that each set, inthe long1- tudinal movement of the tray, will move in a vertical planewith one of the dippers and the respective transfer mechanism. The traysare, as stated, slida-bly supported upon the table 5 and are disposedupon the table in abutment with one. another and are designed to beadvanced with a step by step movement over the surface of the table.This is accomplished by providing guides 109 at each side of the framestructure and slidably mounting in each pair of guides, a block 110which carries a pawl 111 yieldably held by a leaf spring 112, in activeenga ement with rack teeth 113 which are provi ed u on the opposite sidewalls of the trays. Eac block 110 has connected to it a connecting rod114, the other end of which rod is connected to a crank 115 u n thecorresponding end-of a shaft 116 mounted in suitable bearings 117 uponthe base 1 of the frame structure and extending transversely beneath thetable 5. At this point it will be understood that rotation'fof the shaft116 will effect reciprocatory motion of the blocks 110 and therefore, inthe rearward movement of the blocks, the respective pawls 111 will rideover the respective racks 113 and, in the forward movement of theblocks, the pawls will positivelyj engage the rack teeth and causeforward shifting of the respective trays, it being understood that eachtray, in each operation of the shiftin means, is shifted a distanceequal to the distance between the centers of balls supported by therelatively adjacent brid e members of the trays, the said bridge mem ersbeing, however, so spaced as to prevent any contact of the balls onewith another. A sprocket gear 118 is fixed upon each end of the shaft116 inwardly of the crank arm 115, and a sprocket chain 119 is trainedabout each of the said sprocket gears 118 and about a sprocket gear 120formed integral with the hub of the respective gear 41. At this point itwill be evident that inasmuch as the tray shifting means is drivendirectly from the gears 41, the movement of the trays is in consonancewith the operation of the dipping mechanism and the transfer mecha-I11SII1.

It will now be evident that in the operation of the machine, a number ofballs havv ing been dipped and the dippers having been returned to theirelevated position, the transfer units will, in their rotative movement,be automatically operated to cause the gripping members 68 and 69 togrip the respective balls and lift the same from the respective dippers,the engagement of the lower stretches of the several belts 93 with therespective gripping members 68, serving to rapidl rotate the balls asthey pass between their respective guards 96 and 98, during which timethe members 57 of the cams 48 are riding over the opposite sides of theportions 49 of the cams 47. In the operation .of the machine, and afterthe grooved peripheries of the gripping members 68 of the severaltransfer units have left the lower stretches of the belts 93, thetransfer units will begin to swing downwardly in the direction of thetrays, and at this time the trays are stationary. As the grippingmembers of the several transfer units reach a position substantiallyimmediately above the bridge member which is then positioned to receivethe dipped and coated balls, the portions 57 of the cams 48 will ridealong the curved edge portions 52' III of the cam portions 51 of thecams 47 and the ipping members 68 and 69 will be relativeg separated soas to release the balls and deposit them u on the sets of studs 107carried by the bri ge member 104 referred to. As soon as the balls havebeen deposited and released, the tray shifting mechanism will becomeactive to shift the trays so as to bring another bridge member inposition to receive the next balls to be dipped, and it will be evidentthat as the gripping members 68 and 69 are traveling upwardly andrearwardly past the opposite sides of the'respective trough extensions14, the portions 57 of the cams 48 will be riding in engagement with theedge portions 54 of the cam portions 51 of the cams 47, thereby holdingthe grippin members separated until they have reache a position directlyat opposite sides of the respective ball which has, in the meantime,been dipped and elevated to position to be taken up by the transferunit. The 0 eration 1S rendered continuous and it will e evldent that aseach tray becomes filled with dipped balls, it will, in the meantimehave been advanced to a position where it can be readily removed fromthe projecting forward portion of the table 5 and the balls thustransposed to a suitable place where they may be permitted to dry, thestep by step advancement of one tray over the table 5 resulting, ofcourse, in advancement of the tray which has been filled with dip (1balls.

It will be understoo of course, that any desired number of the dippingand transfer units may be built into the machine so that the capacity ofthe machine may be as great as desired. It will also be evi ent that dueto the construction of the transfer units and the capability of thegripping members thereof separating to a greater or less extent, themechanism 1s not restricted to the dipping and coating of golf balls ofany definite diameter, but all of the standard sizes of balls may be desited in the hopper 7 and operated upon y the machine regardless oftheir diameter.
